How many chromosomes are there in a human body cell? There are 46 chromosomes (23 pairs) in a human body cell with the exception of the sex cells. One of each pair is inherited from the mother's egg, the other from the father's sperm. When the sperm and egg unite in fertilization, they create a single cell, or zygote, with 46 chromosomes.
